All Implemented Interfaces:

java.lang.Iterable<E>, java.util.Collection<E>

public class ShrinkableCollection<E>
extends java.lang.Object
implements java.util.Collection<E>

A Shrinkable Collection. This class provides a wrapper for a list of collections that allows items to be removed from the wrapped collections (shrinking) but does not allow items to be added to the wrapped collections.

The collections must act as sets in that each collection in the list must not have two entries which are equal.

All the optional Collection operations except add and addAll are supported. Attempting to add to the collection will result in an UnsupportedOperationException.
